MICH/#EL S. MAsm/Korr /NLENTOR A TTORNEY shown). The camera 1 serves asa reflecting the lamps inside of the reflecting chamber 1, and the cover9 closed again (itv may be connected to the chamber 1 by means of hinges29), plugs 25 replaced, and the Whole device becomes closed into acompact package as shown .in Fig. 3,

I have found that with my art camera of a comparatively small size, forinstance, 21/2x41/2x81/2 inches, when closed, very good enlargements canbe made from small snapshots of about 2X2 or less, enlarging them toabout 10x10, enlargement being successful in sizes from 4 to 8 times ofthe original. Any ordinary kodak may be used of a suitable size.

The ratio indicated may differ Widely, however, depending on the kind oflamps used, also on the quality of the original plctures, and I havealso obtained good enlargements in sizes of 14x17 and 14x21.

Im ortant advantages'of m art camera are, t at it can be used inconJunct-ion with anysuitable ordinary photographic camera, is verysimple and compact, can be folded into a small-portable' package, can beused With ne atives and with positive pictures of any kin and size, andis cheap to manufacture.

A handle 30 may be used for convenience in carrying my camera whenfolded.
